This British Standard specifies requirements for the safe provision and assembly of electrical power, data and telecommunications distribution systems in office furniture, educational furniture and office screens. Requirements are specified for furniture for general use and for furniture for use with specific equipment, parts of which may be built in during manufacture. Appropriate tests are described for the installed power distribution system in the furniture. The standard applies to single‑phase electrical power distribution systems operating at rated voltages up to 250V a.c. that are connected to the fixed wiring of the permanent installation of the building by a 13A fused plug and socket outlet arrangement conforming to BS1363 . The standard makes provision for the routing of cables through the furniture. This standard does not apply to electrical appliances used with or within an article of office furniture or educational furniture, for which appropriate standards are available. The standard does not apply to power distribution systems that are permanently connected to the building installation. The standard also does not apply to special purpose workstations in laboratories or workshops.
